ASVAB Waves, Sound & Light

Episode 24 - WAVES, SOUND, AND LIGHT. Almost at the finish line. This is deep physics territory. Waves transfer energy without transferring matter. Sound waves need a medium. Light waves don't - they travel through the vacuum of space. The electromagnetic spectrum runs from radio waves to gamma rays, and visible light is just a tiny sliver in the middle. What you'll learn: Transverse vs longitudinal waves Wavelength, frequency, amplitude The electromagnetic spectrum: radio, microwave, infrared, visible, UV, X-ray, gamma Reflection, refraction, diffraction Military application: radar, night vision, electronic warfare, comms The military runs on the electromagnetic spectrum. Radio comms, radar, GPS, jamming, electronic warfare - it's all waves. Controlling the spectrum is controlling the battlefield. Some waves you can see. Some you can't. Some you can feel. The most powerful forces are often the ones that are invisible. #ASVAB #Waves #Light #Sound #ElectromagneticSpectrum #GeneralScience #Physics
